Title: Domestic water heating apparatus
Inventor: GLEDHILL HOUGHTON AINSWORTH
IPC: F24D3/08
Filed: 1996-09-11
Abstract: In domestic thermal storage water heating apparatus, a heat exchanger (33) is used for transferring heat between primary water pumped from the thermal store (10) and secondary water which is mains driven (38) through the heat exchanger. To control the temperature of the secondary water which flows from the heat exchanger, the flow of primary water through the heat exchanger is controlled dependant upon that temperature, the temperature being measured by a thermistor (42). Specifically, the primary flow is either throttled dependant upon that temperature or the pump speed is controlled dependant upon that temperature, but in either case, the pump (34) is supplied with sufficient voltage that it will be driven even if the demand for secondary hot water is very low, e.g. in the order of two or three litres per minute or less.

Abstract: Apparatus and process for digital printing images in annular-radial coordinates onto discs. Apparatus is provided for digital printing images in annular-radial coordinates onto discs having an axis of rotation, the printing to occur between an inner radius R 1 of the disc and a outer radius R 2 of the disc. The Apparatus includes a linear printhead array extending radially of the disc at least between inner radius R 1 and outer radius R 2 ; and a drive adapted to rotate the disc about the axis while the printhead is imagewise addressed to create a imaged area that is symmetric to the center of the disc. The drive is adapted to rotate the disc at an annular velocity such that the spatial resolution of the printed image along the outer edge of the image is the same as that of an original image being printed. The image area may be continuous about substantially the entire annular surface of the disc or divided into discrete sections to be printed in associated tiles located on the disc such that:  (x i ,y i )* prime *(r i ,* small Greek theta *i ),  where (x i , y i ) are local coordinates of the center of the associated tile, and * small Greek theta *i is determined by a radial line through the center of the associated tile. Generally, the lower comers of the tiles would not overlap each other. Each pixel having a position (x, y) within each tile is translated to a polar coordinate (r, * small Greek theta *) on the disc by the following two equations:  x-x i = r sin(* small Greek theta *-* small Greek theta *i )  y-y i = r cos(* small Greek theta *-* small Greek theta *i ) - r i .  r 2 /r 1 =R 2 /R 1 .

IPC: B60R21/26
Filed: 1998-12-16
Abstract: A seat belt retractor has an electric motor 10 for retracting and protracting the seat belt. When protraction of the seat belt is detected, an MPU 14 controls the motor 10 to protract the seat belt. The MPU 14 may also control retraction of the seat belt to a predetermined limit and then subsequently protract the seat belt for a predetermined time period for greater occupant comfort. Retraction and protraction of the seat belt may be made dependent on detection of rough road conditions, dozing of the driver, door opening and closing, travelling speed and an impending collision. In a further embodiment activation of an air bag is based on the speed of protraction of the seat belt. The voltage across, and current through, the motor 10 can also be monitored for control and diagnostic purposes.
